WINDOW CONSTRUCTION.

Application filed December 15, 1926. SerialiNo. 154,877.

This invention relates to a window construction and has special reference to a window construction wherein a sash is pivotally and slidably mounted in a frame.

More particularly this invention relates to a window construction in which the sash is pivotally and slidably mounted in the frame in such manner that the sash is sealed when the window is closed or in a vertical pos tion and unsealed when it is desirous of operating said sash on its pivotal construction.

In the present window construction, many hazards are encountered in the cleaning and repairing of windows, and this is especially true in all buildings of several stories where the workman must sit on the outer window ledge while working. In the use of our novel window construction, the workman may stand on the floor and face the window from the inside of the room or other enclosure and when necessary operate the window or sash 011 its pivotal construction and bring the outside of the window into a reverse position, that is, the outer side of the window can become the inner side, whereby, of course, it is readily accessible for the required cleaning or repair. 7 Further, the upper window sash may be drawn down and pivoted to a position which is within the easy reach of the workman thereby obviating the use of ladders and other articles otherwise necessary for work on the upper sash.

One of the objects of this invention is to provide a window construction wherein a sash is pivotally and slidably mounted within a frame-work.

A further object of this invention is to provide a window construction having means whereby the sash is sealed within a frame, said sash being pivotally and slidably mounted in said frame and the sealing means being operable into and out of engagement with said sash.

Further objects of this invention will be apparent from the description and accompanying drawings forming a part of this specification to which reference may now be had for a more complete understanding of the characteristic features of this invention,

and in which drawings:

Figure 1 is a perspective view of a portion of the window construction embodying this invention;

Fig. 2 is a side elevational view of the window construction showing the frame thereof'in section;

Fig. 3 is a sectional view on the line 3 -3 of Fig. 2;

Fig. i is a sectional view taken on the line 6 l4 of Fig. 3;

Fig. 5 is a view similar to Fig. 42 but showing a changed position of one of the operable parts thereof; and

Fig. 6 is aside elevational View partly in 6 section showing in detail the pivotal construction.

Referring now particularly to the drawings, a pair of sashes 10 andll areshown mounted in a frame 12, these sashes con1- 7 prising the usual form of sash construction. Said sashes 10 and 11 are mounted in different planes in the frame 12, as is the usual method of construction, known as the check rail window, whereby the sash 10 may be 7 lowered and the frame 11 may be raised independently of each other. The frame 12 is provided with a pair of grooves 13 and 14 on each vertical side, and are adapted to receive plates 15 which are in sli dable 8 engagement therewith. The plates 15 in turn have plates 16 suitably fixed thereon, as by means of screws 17, said plates 16 extending outwardly beyond the outer edges of said frame. A hearing member 18 pro- 8 jects from said plates 16, and is preferably disposed centrally thereof and integrally therewith.

The slidable plate 15, upon which the bearing member 18 is carried, is fixed to one 9 end of a rope or other suitable means, while the other end of said rope having the usual weighted members (not shown) is attached thereto.

The sashes 10 and 11 are provided with apertures into which are positioned sleeves 20 for engaging the bearing member 18. These sleeves 20, which are preferably of metal, are disposed centrally of said edges, although it is to be understood that this positioning may be varied at will, and the sleeves disposed adjacent either end of the sash, or otherwise.

In the operation of the device thus far described, the sashes may be raised or low- 1 ered in the frame and be guided in their movement by means of the engaging plates 15 sliding in the grooves 14. In any of the positions into which these sashes may be moved, sashes may be revolved their 1 of the frame 12,

the sash. has engagement with the vertical edge of the frame, it is desirable to pro-.

pivots so that either side of the sash or win dow may be exposedto the inside of the en closure in which the frame 12 is positioned. Since the plate 16 projects from the edge and as the vertical edge of vide a recess 21 in said'sash for receiving the plate 16, said recess to be of'a size that will permit the sash to revolve about the fixed-plate 16.

In order that thesash es may be in asubfstantially sealed relation with the frame when in a closed position, the frame is v and inner ed es of the sash members. Elon-v provided with slots 22 adjacent the outer gated strips 23 of anysuitable material are disposed within these slots 22.

inner edges of the sash members, thereby effecting a sealed relation between the sash members and the frame.

in order tomanually operate these strip members into and out of engagement with the sash members, a crank arm 24f. is mounted within a frame in any suitable manner, as

for instance, being journalled in the bearing members 25,the arms of said cranlrmem bersengaging slotted portions 26 in pro ect ons 27 formed preferably integrally with the strips 23. These pro ecting portions 27 are provided'with suitable openings 28 into which they are received when the strips are drawn back out of engagement with the sash members. The crankmembcrs are preferably disposed adjacent the.

upper and flower ends of said frame, as

r shown in Fig. 2 ofthe drawings.

In the operation of these strips, the crank nien'ibers are rotated from the inside of the enclosure, whereby the arms of sald crank members operate in the slots 26 to push the strips outwardly into an engagement with the outer andinner ends of thesash members, and operate bya reverse rotationof the crank members to draw the strips out of engagement with the inner and outer ends of the sash members, as clearly shown in Figs. at and '5iof the drawings. This construction seems to be the most simple, al-

though it will be apparent that various means for actuating these strip members may be utilized, this construction being shown for purposes of illustration to indicate the operable arrangement of the members.

'. While we have described but a single embodiment of this invention, it is to be understood that various modificationsthereof will be apparent to those skilled in the art without departing from the spirit and scope of this invention, and therefore, it is desired thatthe same be limited only by thev scope of the appended claims and the priorart.

\Ve claim: 7 1.'A window construction comprising a' frame havinggrooves on each 'vertica-l'side 7 thereof, a plate for engagement with each of said grooves and not extending beyond the outer edges of said frame, a plate having a bearing member extending therefrom and secured to said first mentioned plates, a sash pivot-ally mounted on said bearing members and disposed in said frame whereby a snug engagement exists between the edges of said frame and said sashin anormally'closed posit-ion, said frame havingslots adjacent'the outer and inner edges of said sash, and elongated strips for slidable engagement horizontally 'of said slots and extending over said outer and inner edges of said sash in one position thereof to substantiallyseal said sash and saidframe. i 1- 2. A window constructioi'rcomprising a frame having grooves on each vertical side thereof, a plate for engagement with each of said grooves and-not extending beyond the outer edges of said frame, a plate having a bearing member extending therefrom and secured tosaid first mentioned plate, a sash pivotally mounted on said bearing members and having a cut-away portion into which said second mentioned plate is reeived whereby a snug engagement exists between theedges of said frame and said sash in a normally closed positioinsaid frame having slots adjacent the outer and inner edges of said sash, elongated strips for slidable engagement with said slots,and a crank arm supported in said frame and for engagement with said projections whereby said strips are moved into and out of engagement with the edges of said sash. i

In witness whereof we have hereunto subscribed our names;
